Abstract

A light source module (12) has a reflector (14) having a light reflection face (14a) and a plurality of light emitting elements (11). The light reflection face (14a) is curved in a circular arc shape in a width direction of the reflector (14) and extends in a longitudinal direction of the reflector (14). The light emitting elements (11) are arranged in a center portion in the width direction of the light reflection face (14a) and are arranged linearly along the longitudinal direction of the reflector (14).
